Can you use cyclosporine chronic use?

If prescribed: If you are under the care of a doctor and require the use of Cyclosporine chronically, then yes, you can use it.

Needs monitoring: Cyclosporine is a calcineurin inhibitor and it has a narrow therapeutic index. If the blood level of cyclosporine is too high, it is likely to cause adverse effects which include nephrotoxicity, hyperlipidemia, gingival hyperplasia, and hair growth. Whether it is used as an anti-rejection agent or as an immunosuppressant in treating auto-immune diseases, one needs to have a close follow-up.
